TiVo has extended the lifetime transfer offer. Now you can purchase the Series3 on or before 01/31/2007 and activate it by 03/02/2007. So if you were debating it and didn’t buy before the end of the year, you have another month. Updated details at: http://www.tivo.com/vip
EDIT: Of course, right after I posted I saw this post at WeaKnees Blog. It looks like the lifetime transfers from DirecTiVo boxes are once again NOT allowed. So the door has closed on those.
